VVV Survey Microlensing Events in the Galactic Center Region
(Institute of Physics Publishing, 2017)
We search for microlensing events in the highly reddened areas surrounding the Galactic center using the near-IR observations with the VISTA Variables in the Vía Láctea Survey (VVV). We report the discovery of 182 new ...
Stellar density profile and mass of the Milky Way bulge from VVV data
(EDP SCIENCES, 2016-03)
We present the first stellar density profile of the Milky Way bulge that reaches latitude b = 0 degrees. The profile was derived by counting red clump stars within the colour-magnitude diagram that was constructed using ...
Mapping the outer bulge with RRab stars from the VVV Survey
(EDP SCIENCES, 2016-07)
Context. The VISTA Variables in the Vía Láctea (VVV) is a near-IR time-domain survey of the Galactic bulge and southern plane. One of the main goals of this survey is to reveal the 3D structure of the Milky Way through ...
Structure and kinematics of Type II Cepheids in the Galactic bulge based on near-infrared VVV data
(EDP Sciences, 2018-11)
Context. Type II Cepheids (T2Cs) are radially pulsating variables that trace old stellar populations and provide distance estimates through their period-luminosity (PL) relation. Aims. We trace the structure of old stellar ...
